Preheat the oven to 350°F (175°C) and grease an 8x8-inch baking pan.

In a medium bowl, whisk together flour, cocoa powder, granulated sugar, brown sugar, and a pinch of salt.

In another bowl, combine melted butter, eggs, and vanilla extract until well mixed.

Pour wet ingredients into dry ingredients and stir until just combined.

Pour batter into the prepared pan and spread evenly. Bake for 25-30 minutes or until a toothpick comes out with moist crumbs.

Allow to cool before cutting into football shapes and decorating with frosting.
